＜正＞Herrnstein experimentally studied the choice behavior of pigeons on a special reinforcement schedule,the concurrent variable interval（CVI） schedule,and found a famous matching *** empirical behavior law is remarkably conserved across many kinds of species,but it has been viewed as an irrational behavior,which means that the matching behavior does not maximize *** this paper,we succinctly demonstrate that any strategies leading to matching law can obtain maximal rewards for the CVI reinforcement schedule in discrete time *** addition,we put forward a novel strategy algorithm that can earn the maximal reward in the CVI reinforcement *** results reveal that the matching behavior can be seen as a rational behavior in the reinforcement schedule.

为了解决国民经济动员实战演练高成本、低灵活性、低协同性问题,研制基于HLA的分布式国民经济动员仿真演练系统成为有效途径。为了满足演练对象、流程及功能的高度复用、动态配置与灵活扩展的需求,具有RTI联邦成员、演练角色及演练系统三级封装特性的分层架构则是系统实现的必要条件。首先应用角色建模与业务用例建模方法抽象了演练对象与流程,其次基于分层设计模式设计了系统软、硬件体系结构,最后针对系统技术路线进行了分析。

Shared Control Teleoperation for Targets Acquisition

第2.届中国控制与决策会议

作者： WANG Dongli 1 , LIU Huaping 2., SUN Fuchun 2., DU Yonggui 1 1. Automation college of information engineering, Taiyuan university of technology, Taiyuan 03002., china2.

It is very difficult to capture the target in the microgravity environment, simply by relying on ground operators. Based on shared control theory, this paper effectively combines the decision-making ability of ground operators and the independent ability of space robot, through making full use of independent control ability of the space robot, and reducing operators’ workload and working time, to achieve more valid capture for targets. Shared control is more accurate capture of the target compared with teleoperation in experimental.

Recently, experiments have demonstrated that simple binary arithmetic and logical operations can be computed by the process of self- assembly of DNA tiles. In this paper, we show how the tile assembly process can be used for subtraction and division. In order to achieve this aim, four systems, including the comparator system, the duplicator system, the subtraction system, and the division system, are pro- posed to compute the difference and quotient of two input numbers using the tile assembly model. This work indicates that these systems can be carried out in polynomial time with optimal O(1) distinct tile types in parallel and at very low cost. Furthermore, we provide a scheme to factor the product of two prime numbers, and it is a breakthrough in basic biological operations using a molecular computer by self-assembly.

ON ENHANCING KATZ-SMOOTHING BASED BACK-OFFLANGUAGE MODEL

6～(th) International Conference on Spoken Language Processing

作者： Jian Wu and FangZhengCenter of Speech technology State {2. {2. of intelligent technology and systems Department of Computer Science and technology. Tsinghua University Beijing china

＜正＞Though the statistical language modeling plays an important role in speech recognition, there are still problems that are difficult to be solved such as the sparseness of training data, Generally, two kinds of smoothing approaches, namely the back-off model and the interpolated model, have been proposed to solve the problem of the impreciseness of language models caused by the sparseness of training data. By expanding the idea of interpolation model to Katz-smoothing based re-estimation of the

＜正＞Transductive inference is well suited for text categorization tasks with an enormous amount of unlabeled data in addition to a small number of labeled data. We present here a new transductive support vector machine approach for text categorization in order to make use of the large amount of unlabeled data efficiently. In our experiments the performance of transductive methods greatly exceeds that of conventional SVM. Experimental results also show that our algorithm outperforms Joachims’ TSVM, especially when there is a significant deviation between the distribution of training and test data.

作者： Xingli Huang JihongZhu ChunhuaHu PeifaJia State key {2. of {2. technology and systems Department of Computer Science and technology Tsinghua University Beijing 100084 china

＜正＞This paper presents the nonlinear control of a small unmanned tandem helicopter. Based on the 12.states nonlinear mathematical model of the small unmanned tandem helicopter, using the forced singular perturbation theory, the complicated dynamic system is divided into two reduced order subsystems, the slow dynamic subsystem and the fast dynamic subsystem. With the dynamic inversion theory, the nonlinear control laws of these two subsystems are designed respectively. The simulation results indicate that this control scheme is suitably.
